Physics – Case Study

A zero.01 kg bullet is launched with a muzzle velocity of 850 m/s. It’s fired from a 308 Winchester with a mass of three.2 kg. What’s the recoil velocity of the weapon?
A zero.01 kg object is 200 meters above the bottom. What’s its potential power?
An athlete in coaching can run up a flight of stairs in 10 seconds. If he weighs 800 N and climbs a complete peak of four.zero m, how a lot energy does this require?
A ball is thrown straight up with an preliminary velocity of 17.zero m/s. How excessive will the ball journey above the purpose the place it leaves the thrower’s hand when it stops shifting up? Ignore air resistance.
Calculate the warmth power (in energy) required to make a pot of espresso containing 750 g of water that warms from 23°C to 99°C. The particular warmth capability for water is 1 cal/(g⋅°C)
